wmnow-nn eunaron mncnaivism Application filed March 24, 1927. Serial No.178,082.

The invention relates to window regulator mechanism and refers moreparticularly to ments of parts as window regulator clutches. One of theobjects of the invention is to provide an improved mechanism which maybe cheaply manufactured and assembled and which is so constructed thatthe driving and driven members of the clutch are effectively held inalignment. Another object is to so construct the mechanism that thedriven member is journaled upon a pin secured to the support and forminga bearing for the driving member. With these as well as other objects inview, the invention resides in the novel features of construction andcombinations and arrangemore fully hereinafter set forth. n

In the drawings Figure 1 is an inside elevation partly broken away of aportion of a motor vehicle 1 door havingapplied thereto a windowregulator mechanism embodying my invention;

Figures 2 and '3 are enlarged cross sections respectively on the lines2-2 and 3 3 of Figurel; I Figure 4 is a cross section on the line ofFigure 2. The window regulator illustrated. in the present instance hasthe mounting'plate 1 which is secured to and depends from the lock board2 of the door. 3 is the lifter arm of the window regulator ri idlysecured to the gear segment'4 which is pivotall mounted at 5 upon themounting plate 1; 61s the pinion meshing with the gear segment and '7 isthe handle or crank for. actuating the pinion. which in turn actuatesthelifte arm through the gear segment. I

For the purpose of locking the lifter arm in its various positions ofangular adjust ment when driving force is no longer applied 7 throughthe handle or crank and at the same time to provide for releasing thelock when driving force is applied through the handle or crank, I haveprovided the following clutch mechanism- 8 is a cup having the an-.

nular flange 9. at its outer end secured to the lock board 2 and.the'annular flange 10 at its inner end terminating in the cylindrical;

flange 11. 12 is :1 lug either integral with or secured to themountingplate land located.

on the opposite side of the mounting platev from the cup 8 and spacedfrom the latter.

.Ishaped member is provi drical flangell of the cup and has the head14'within the cup and preferablyprovid'ed with the diametricallyopposite peripheral recesses 15. is a pin in axial alignment with thedriving member 13"and also the cup 8 and preferably fixedly secured atits outer Y end to the lug 12 as by being riveted over thereagainst toclampthe lug against the an nular, flange 17 1 upon the pin. This inextends axially into the head 14 of thed riving merfiber and terminatesreferably within the cylindrical flange 11,-t e head being:journaled'upon the pin. As a result it will be seen that the drivingmember is'journaled at spaced points so that it-will be .properly heldfrom movement relative to the cup. v

The pinion 6 is also journaled uponthepin 16 andis located betweenthelug 12 and the outer end of the-head 14. For driving this pinion fromthe driving member, I have provided the cup-shaped member 18 whichispreferably .formed of sheet metal and has its base rigidly secured tothe inion. This clip- I died with the diametrically opposite lateralprojections or arms19, either of which is adapted to extend into therecess 15 formed inthe head 14, the.

,other at-this time being located on the'opposite side of the head.Both'ithe lateral projections 19 and theiends of the head 14a-reroundedto present-peripheral faces concentrio of the cup 8 andspacedtherefrom a dis tance to rece vethe coil spring 20 and furtherrovide" clearance bet-ween this s ring and t 1e cup or this spring andthe perip eral faces. The spring has'the inturned ends 21 engaging inthe-recess 15 of the head 14 and at opposite sides of the lateralprojection 19, the arrangement being such that upon driving force beingapplied through the handle or crank 7 the head 14 engaging one of thein-.

turned ends 21 of the coil spring 20 contracts this spring and. releasesthe look, after which this inturned end engages the lateral projection19 engaging in the recess in the head and through the cup-shapedmember'18 rotates the "pinion 6 to angularly adjustthe lifter arm.However, when driving pressure upon .the handle or crank is released anddriving pressure is applied upon the pinion within the cup 8 adjacentits annular flange 10 and preferably secured to the driving member 13 atthe innerend of its head 14, this cup-shaped member having the annularflange portion 24 opposite the inner end of the coils ring.
